SPECIFICATION forming part of Letters Patent No. 323,880, dated August 4, 1885.

Application filed December 31, 1883. (No model.)

To all whom it may concern.-

Be it known that I, SILAS R. OWEN, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Cutting Apparatus for Harvesting-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to the letters of reference marked thereon, which form a part of the specification.

The invention relates to improvements in cutting apparatus for harvesting-machines; and it consists in the construction, combination, and adaptation of parts, as will be hereinafter more fully set forth, and specifically pointed out in the claim appended.

The main object of my invention is to improve devices of the character referred to, so as to reduce the strain and consequent wear and tear upon various parts thereof, and to secure a lighter-draft machine without a reduction of cutting capacity. These objects I accomplish by the mechanism shown in the accompanying drawings, in which- Figure l is a plan view ofthe endless cutting apparatus and its frame removed from the machine. Fig. 2 is a View of a side elevation of the same, partly in section. Fig. 3 is a sectional view taken on the lines y y of Fig. 1 and partly broken away. Fig. 4 is a plan view of two of the cutting-teeth and their connecting-bars, and Fig. 5 is a view of a side elevation of the same. Fig. 6 is a plan view of my invention, showing the same applied to a mowing-machine. Fig. 7 is afront elevation of the same, and Fig.8 is a cross-sectional view taken on the lines as w of Fig. 6.

Referring by letter to the drawings, A indicates the frame of a mowing-machine, which may be of any ordinary or approved construction; and 15,0neof the driving and supporting wheels thereof, which is secured to the axle D. E is a bevel-gear, which is keyed on the said axle, and engages a smaller bevel-gear, H, which is fixed to one end of a shaft, F, which is arranged at right angles to the shaft D, and is supported in said frame. The shaft F is which is secured the finger-bar b. In the very tical arms or branches of this frame is journaled a horizontal shaft, L, which is provided about midway its length with a fixed vertical bevelgear, M, which is journaled to the hanger-lugs V V by means of journal-boxes T, as shown. This frame It is also provided beneath the shaft L with a transverse bar, S, through which passes a short vertical shaft, f, carrying atits upper end a fixed bevel-pinion, g, which engages with the bevel-gear M on the shaft. To the opposite or lower end of this vertical pinion-shaft f is secured a chainwheel, 0, and is arranged on the fingerbar b, so as to drive the endless cutter, as will be presently explained.

It will be perceived that the shaft L is arranged parallel to the shaft F, and is provided at its outer end with a chain-wheel, P, by which, through the medium of an endless chain, N, mot-ion may beimparted to the cutting apparatus received from the gear on the driving-axle.

It will be readily seen that my improve ments may be applied to any mower without impairing its usefulness or altering its construction in any manner whatever, and the shaft L, as well as serving as a medium for transmitting motion from the mower to the cutting apparatus, serves as a hinge-joint whereby the said cutting apparatus may be adjusted at various angles to the machine and adapt itself for unevenor undulated surfaces.

To attach the cutter to the machine the boxes T are first removed and the journals of the shaft L placed in the lughangers, after which the boxes are I'( placed and firmly bolted again, as shown more fully in Fig. 8.

a represents a sectional jointed band, carrying cutting-sections b, which rotate upon band-wheels or pulleys O O, which are journaled at each end of the finger-bar b. One

end of this finger-bar is provided with a central longitudinal slot, in which is arranged a rectangular slide, 6. adapted to be moved in and out within the slotby means of a threaded rod and thumb-nut, e, the object being to regulate the tension of he jointed cutting band by moving the pulley C, which is journaled in the said slide. This finger bar I) is provided with a circumierential recess. 7), to partially receive the cnttingsections and the flat bars connecting the same, whereby they may be kept perfectly straight and prevented from sagging during operation. a indicates flat bars for connecting the cutter-sections. These bars are provided at opposite ends with vertical circular apertures, and the alternate ends of the tangs of the cutters are also recessed to receive the bolt which connects the The heels or tang-s of the cutterplates a.
